Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment dosing device. Background Art

[0002] With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If sewage cannot be completely purified and is directly discharged, it will re-enter the earth's water cycle system, destroying the ecological environment. Sewage will also enter the human body and affect human health. Failure to filter sewage will cause solid pollutants to be contained in sewage, resulting in the inability to purify solid pollutants in time, making sewage discharge substandard. In addition, sewage cannot be recycled and purified, resulting in low purification effect.

[0003] However, in the prior art, during the use of traditional sewage treatment dosing devices, since most of them use drugs to treat sewage, the sewage and drugs react naturally, resulting in a short contact time between the drugs and sewage, which leads to a long reaction time between the sewage and the drugs, affecting the sewage treatment effect of the equipment and reducing the sewage treatment efficiency of the equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the utility model to solve the technical problems is: a sewage treatment dosing device, comprising: a workbench; a stirring tank, the outer wall of the stirring tank is fixedly connected to the inner wall of the workbench; a feeding device, the outer side of the feeding device is fixedly connected to the inner wall of the stirring tank; a filtering device, the top of the filtering device is fixedly connected to the bottom of the stirring tank; a water inlet hopper, the inner wall of the water inlet hopper is fixedly connected to the top of the stirring tank; wherein the feeding device comprises a dosing hopper, the bottom of the dosing hopper is provided with a rotating rod, the outer wall of the rotating rod is rotatably connected to the inner wall of the stirring tank, the outer wall of the rotating rod is fixedly connected to a rotating cylinder, the outer wall of the rotating cylinder is fixedly connected to a mounting plate, the mounting plates are provided in three groups, and the outer wall of each group of the mounting plates is symmetrically fixedly provided with an infusion tube, the outer wall of the infusion tube is fixedly connected to The medicine enters the medicine feed pipe through the medicine feed pipe, and the medicine enters the interior of the rotating cylinder under the guidance of the medicine feed pipe. Since the medicine feed pipe extends to the bottom of the inner cavity of the rotating cylinder and the interior of the infusion tube is connected with the interior of the rotating cylinder through the through-holes, the rising medicine will gradually completely immerse the inner cavity of the bottom group of infusion tubes, and each group of infusion tubes corresponds to a group of through-holes. When the medicine is added continuously, the liquid level inside the rotating cylinder continues to rise, and can rise to the bottom of the cover plate at most. Since the cover plate seals the inner cavity of the rotating cylinder, the interiors of the three groups of infusion tubes are filled.

[0005] Preferably, the bottom of the dosing hopper is fixedly connected to the top of the stirring tank, the side of the rotating rod away from the cover plate is fixedly connected to the inner wall of the rotating cylinder, and the outer wall of the rotating rod is rotatably connected to the inner wall of the stirring tank. The operator adds the medicine from the dosing hopper, and the medicine flows into the pipe of the medicine inlet pipe. The medicine inlet pipe passes through the cover plate to slowly inject the medicine from the bottom of the rotating cylinder until the medicine flows into the inner cavity of the infusion tube, and the sewage enters the interior of the stirring tank from the water inlet hopper. At this time, the motor externally connected to the top of the rotating rod is started, the motor drives the rotating rod to rotate, and the rotating rotating rod drives the rotating cylinder to rotate. Driven by the mounting plate, the three groups of infusion tubes drive the nozzle to rotate.

[0006] Preferably, the inner wall of the infusion tube is fixedly connected to the inner wall of the rotating cylinder via a through hole, and the through hole is provided in the wall of the rotating cylinder, the outer wall of the rotating rod is rotatably connected to a support frame via a bearing, the outer side of the support frame is fixedly connected to the inner wall of the stirring tank, and the medicine inside the infusion tube will be accelerated to flow into the interior of the stirring tank under the action of the centrifugal force generated by the rotation, and the medicine flowing out faster will be fully mixed with the sewage under the drive of the stirring fan. Since the stirring fan is correspondingly arranged on the infusion tube, the upper, middle and lower layers of sewage inside the stirring tank are stirred simultaneously under the drive of the rotating cylinder, further accelerating the mixing of the medicine and sewage.

[0007] Preferably, the filtering device includes a drain pipe, a connecting flange is fixedly connected to the bottom of the mixing tank, a water outlet cylinder is fixedly connected to the inner wall of the water outlet cylinder with filter cotton, and the inner wall of the filter cotton is fixedly connected to the filter cartridge. As the equipment stirs, the sewage and the medicine are mixed, and the mixture reacts chemically to adsorb tiny impurities such as pigments, small particles and organic matter in the sewage. The impurities are adsorbed into clusters, and the impurities enter the interior of the filter cartridge, and large-volume impurities are intercepted by it for primary filtration. Since the interior of the filter cotton is provided with an adsorbent, and the interior of the sponge is loose and porous and has a complex structure, the water body can be intercepted and filtered for a secondary time. After stirring, mixing, chemical reaction, static sedimentation, and multi-stage interception and filtration, the sewage is purified by adding medicine, and the purified water is stored in the interior of the water outlet cylinder and finally discharged through the drain pipe.

[0008] Preferably, the outer wall of the filter cartridge is fixedly connected to the inner wall of the mixing tank, the inner wall of the bottom of the water outlet cylinder is fixedly connected to the outer wall of the drain pipe, and the interior of the water outlet cylinder is connected to the interior of the drain pipe.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model is provided with a feeding device. With the continuous injection of the medicine, the interiors of the three groups of infusion tubes are all filled. Since the medicine adding hopper is continuously adding medicine and is affected by gravity, according to the principle of the communicating vessel, the medicine begins to slowly flow into the interior of the stirring tank. The rotating rotating rod drives the rotating cylinder to rotate. Driven by the mounting plate, the three groups of infusion tubes drive the nozzles to rotate. At this time, the medicine inside the infusion tube will accelerate to flow into the interior of the stirring tank under the action of the centrifugal force generated by the rotation. The medicine that flows out faster is fully mixed with the sewage under the drive of the stirring fan. Since the stirring fan is correspondingly arranged on the infusion tube, the upper, middle and lower layers of the sewage inside the stirring tank are stirred simultaneously under the drive of the rotating cylinder, thereby further accelerating the mixing reaction of the medicine and the sewage.

[0011] 2. The utility model sets a filtering device. As the equipment stirs, sewage and medicine mix, and the mixture chemically reacts to adsorb tiny impurities such as pigments, small particles and organic matter in the sewage. As the mixed fluid becomes still, the impurities enter the interior of the filter cartridge, and large-volume impurities are intercepted by it for primary filtration. Since the interior of the filter cotton is provided with an adsorbent, and the interior of the sponge is loose and porous with a complex structure, the water body can be intercepted and filtered for a secondary time. After stirring, mixing, chemical reaction, static sedimentation, and multi-stage interception filtration, the sewage is purified by adding medicine.

[0023] The inner wall of the infusion tube 371 is fixedly connected to the inner wall of the rotating cylinder 35 through the through hole 351, and the through hole 351 is opened in the wall of the rotating cylinder 35. The outer wall of the rotating rod 34 is rotatably connected to the support frame 39 through a bearing, and the outer side of the support frame 39 is fixedly connected to the inner wall of the stirring tank 2. The filtering device 4 includes a drain pipe 45, and the bottom of the stirring tank 2 is fixedly connected to a connecting flange 41, and the bottom of the connecting flange 41 is fixedly connected to a water outlet cylinder 42, and the inner wall of the water outlet cylinder 42 is fixedly connected to filter cotton 43, and the inner wall of the filter cotton 43 is fixedly connected to a filter cartridge 44, and the outer wall of the filter cartridge 44 is fixedly connected to the inner wall of the stirring tank 2, and the inner wall of the bottom of the water outlet cylinder 42 is fixedly connected to the outer wall of the drain pipe 45, and the interior of the water outlet cylinder 42 is connected to the interior of the drain pipe 45.

[0024] Working principle:

[0025] When in use, the workbench 1 is placed on the ground, the medicine enters the stirring tank 2 from the feeding device 3, the sewage enters the stirring tank 2 from the water inlet hopper 5, the medicine-water mixture is stirred and mixed inside the stirring tank 2, and the filtering device 4 performs static separation and filtration on the fluid after the mixed reaction.

[0026] In the above process, first, the medicine enters the interior of the medicine feeding pipe 32 through the medicine adding hopper 31, and follows the guidance of the medicine feeding pipe 32 to enter the interior of the rotating cylinder 35. Since the medicine feeding pipe 32 extends all the way to the bottom of the inner cavity of the rotating cylinder 35, and there is space between its bottom end and the bottom of the inner cavity of the rotating cylinder 35, the two do not contact each other. As the medicine solution is continuously injected, the liquid level inside the rotating cylinder 35 continues to rise. Since the interior of the infusion tube 371 is connected to the interior of the rotating cylinder 35 through the through hole 351, the rising medicine will gradually completely immerse the bottom. The inner cavity of a group of infusion tubes 371 at the bottom, and each group of infusion tubes 371 corresponds to a group of through holes 351, and the medicine is continuously added. The liquid level inside the rotating cylinder 35 continues to rise, and can rise to the bottom of the cover plate 33 at most. Since the cover plate 33 seals the inner cavity of the rotating cylinder 35, the insides of the three groups of infusion tubes 371 are all filled, and the inside of the nozzle 38 connected with each group of infusion tubes 371 is also filled. Since the medicine adding hopper 31 continues to add medicine and is affected by gravity, according to the principle of the communicating vessel, it can be known that the medicine begins to slowly flow into the inside of the stirring tank 2;

[0027] Subsequently, the sewage enters the interior of the mixing tank 2 from the water inlet hopper 5. At this time, the motor connected to the top of the rotating rod 34 is started, and the motor drives the rotating rod 34 to rotate. The rotating rotating rod 34 drives the rotating cylinder 35 to rotate. Driven by the mounting plate 36, the three groups of infusion tubes 371 drive the nozzle 38 to rotate. At this time, the medicine in the infusion tube 371 will accelerate to flow into the interior of the mixing tank 2 under the action of the centrifugal force generated by the rotation. The medicine that flows out faster is fully mixed with the sewage under the drive of the stirring fan 37. Since the stirring fan 37 is correspondingly arranged on the infusion tube 371, under the drive of the rotating cylinder 35, the upper, middle and lower layers of sewage in the mixing tank 2 are stirred at the same time, further accelerating the mixing of the medicine and sewage.

[0028] During the rotation of the rotating rod 34 on the support frame 39, the feed amount of the dosing hopper 31 can be appropriately adjusted and controlled according to the actual liquid level of the sewage outside the rotating rod 34, thereby controlling the discharge of the medicine from the infusion tube 371, and also controlling the concentration of the medicine in the sewage to meet the dosing needs in various environments.

[0029] As the equipment stirs, the sewage and the medicine mix, and the mixture reacts chemically to adsorb tiny impurities such as pigments, small particles and organic matter in the sewage. The impurities are adsorbed into a mass and their dead weight increases. At this time, the equipment stops running. As the mixed fluid is stationary, the impurities gradually settle to the inside of the filter device 4, and the impurities enter the inside of the filter cartridge 44. Large-volume impurities are intercepted by it and primary filtration is performed. Since the filter cotton 43 is provided with an adsorbent inside, and the inside of the sponge is loose and porous, and the structure is intricate, the water body can be intercepted and filtered for a second time. After stirring, mixing, chemical reaction, static sedimentation, and multi-stage interception filtration, the sewage is purified by adding medicine, and the purified water is stored in the water outlet cylinder 42, and finally discharged through the drain pipe 45;

[0030] In order to prevent blockage caused by long-term use, the mixing tank 2 and the water outlet cylinder 42 are connected by bolts and a connecting flange 41. When the internal is blocked or maintenance is required, the nuts and bolts on the outside of the connecting flange 41 can be loosened to complete the separation and disassembly of the water outlet cylinder 42 and the mixing tank 2.

[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
